Title: Cleaning of hollow fibre membranes
Inventor: DRUMMOND HUMPHREY JOHN JARDINE
IPC: B01D65/08
Filed: 1995-09-08
Granted: 2006-11-07
Abstract: A method and apparatus for recovering fine solids from a liquid feed suspension is disclosed. The apparatus has an operating cycle including a concentration part of the cycle in which solids present in the feed suspension are concentrated and a backwash part of the cycle in which supply of feed suspension to the concentrator is interrupted, the concentrator comprises a shell (11), and a plurality of elastic, hollow, microporous, polymer fibres (12) being fixed at their ends within the shell (11). Pressurized feed suspension is supplied to the outside of the fibres curing said concentration part of the cycle and the filtrate may be withdrawn from the fibre lumens during the operating cycle. Tyuring the backwash cycle the concentration part of the cycle is terminated by ceasing supply of feed to said exterior surface of the fibres (12). The shell (11) is then sealed and the remaining filtrate removed from the lumens. A source of fluid under pressure is then applied to said lumens before, at the same time as, or just after opening the shell (11 ) to atmosphere, to cause explosive decompression through the walls of the fibres (12) whereby the fluid under pressure passes through sai d walls. The pressure level in said lumens is maintained at a predetermined value for a sufficient time following said decompression to cause substantial portions of solids lodged within and/or on the fibre walls to be dislodged. The dislodged contaminant matter is then washed away by the application of a flow of liquid over the surface of the fibre walls; and the concentration part of the operating cycle is recommenced by introducing the supply of feed suspension to said exterior surface of said fibres (12).

Inventor: EIFRIG ROBERT O
IPC: H04N7/30
Filed: 1998-02-25
Granted: 2006-01-31
Abstract: DC and AC DCT transform coefficients of an INTRA coded block (310) are differentially encoded by selecting predictor DC and AC coefficients from a left-hand neighboring block (320) and a top neighboring block (340). Each block (310, 320, 340) is coded according to a frame mode, a reordered field mode, and a non-reordered field mode. The AC predictor block is selected according to the respective coding modes of the blocks, and the block in which a DC predictor resides. The top block (340) is selected as an AC predictor when the top block (340) and current block (310) are both reordered field mode, or both frame mode and/or non-reordered field mode, and the DC predictor resides in the top block. Zeroed AC spatial transform coefficients are used in place of the AC spatial transform coefficients from the selected block when the selected block is not INTRA coded, or does not reside in the same Video Object Plane (VOP) as the current block. DC coefficients may be non-linearly quantized.

Granted: 2011-04-26
Abstract: An improved process for producing a polymer by polymerizing a monomer having an ethylenic double bond in a polymerization vessel having a polymer scale preventive coating film on its inner wall surfaces, etc. is provided. The coating film is formed by coating a first coating liquid containing a compound selected from the group consisting of an aromatic compound having 5 or more conjugated .pi. bonds and a heterocyclic compound having 5 or more conjugated .pi. bonds, and then coating a second coating liquid on the first layer. The first and second coating liquids are applied by means of steam as a carrier. The second layer has a surface having a contact angle to water of less than 60° after its surface has been brought into contact with a solution of mixture of water and a vinyl chloride monomer in a weight ratio of 1:1, at 50°C for 1 hour. This process can shorten the time for forming the coating film to improve productivity, can improve the effect of preventing adhesion of polymer scale, can make colored particles less mix into polymer products obtained by this process, can lessen fish eyes and initial discoloring of formed products and can improve the quality of polymeric products and their formed or molded products.

Abstract: A fast-converging, computationally simple, method for recognizing a single frequency tone or a sinusoid in a signal without prior knowledge of the tone frequency. The method employs a second order or higher auto-regressive model and includes: (a) sampling the signal at a constant sampling rate, and, for each sample, recursively determining a finite number of correlation coefficients using a time-reversed, exponentially weighted, future sliding equivalent of the signal, wherein the correlation coefficients are determined using pre--existing values of the correlation coefficients determined in a previous iteration, a current sample of the signal and at least two consecutively previous samples of the signal; (b) periodically determining at least the second auto-regressive coefficient modelling the signal using the correlation coefficients; and (c) recognizing the presence of the tone based on the value of the second auto-regressive coefficient.
